Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent accidental engagement of the brake system.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Slide the caliper off the rotor and support it to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare the old pads with new ones to ensure proper fit.
Clean the caliper bracket and apply brake grease to the backing of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

4. Reinstall Brake Caliper

Carefully compress the caliper piston using a brake caliper tool to ensure it fits over the new pads.
Reattach the caliper and tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-25 ft-lbs).
Ensure all components are aligned and secure.

5. Reattach Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

6. Test Brakes

Reconnect the battery and pump the brake pedal several times to seat the brake pads.
Test drive the vehicle at low speeds to ensure proper operation and check for any abnormal noises or pulling.
